1. An image forming apparatus comprising:
a rotatable image bearing member;
a developing device that supplies a developer to a surface of the image bearing member;
a cleaning member that comes into contact with the surface of the image bearing member to form a contact region, the cleaning member removing the developer from the surface in the contact region;
a collecting container that collects the developer removed by the cleaning member, the collecting container having a discharge port for discharging the developer; and
a control portion that can execute a supply mode during a non-image-forming period, the supply mode in which a region of the image bearing member that is supplied with the developer from the developing device passes through the contact region with rotation of the image bearing member to allow the cleaning member to supply the developer into the collecting container,
wherein the discharge port is provided between a first end portion and a second end portion, which the first end portion is one end portion and the second end portion is another end portion of the image bearing member in a direction of a rotation axis line of the image bearing member, and
wherein the control portion performs control such that a portion of the region that is supplied with the developer in the supply mode overlaps, in the direction of the rotation axis line, a position where the discharge port is provided.
